S. GREENE, of

new and useful Improvements in' Photographic-Print-Treating Apparatus; and I the following to be a full, clear, and exact description of the same, reference being had'to the accompanying drawings, forming apartof this specification, and to the reference-numerals marked thereon.

My present invention relates to photography and more particularly to the treatment of photographic prints and negatives in liquid baths, and it has for its object to provide improved means for efiecting a quick transfer of the prints from one recep tacle to the other which will offer greater convenience to-the operator, prevent injury to the print and insure .its'proper immersion in the bath. t

A further object of the invention is to provide an apparatus of the character indicated'adapted for the day-light method of treating the prints, particularly when fed to the apparatus from an automatic or mechanical device, such as a camera, that exposes a strip of sensitized material, severe the exposed portion. and delivers it for treat 'ment.

To these and other ends the invention consists'in certain improvements and combinations of parts all as will be hereinafter more fully described, the novel features being pointed out in the claims at the end of the specification.

In the drawings: Figure 1 is a longitudinal central section through a treating apparatu constructed in accordance with and illustrating one embodiment of my invention, the parts being shown in one position; Fig. 2 is a similar view with the parts in another position; Fig. 3 is a top plan view pf one of the receptacles, and Fig. 4 is a detail, enlarged section taken substantially on the line 44 of Fig. 3.'

Similar reference numerals throughout the several figures indicate the same parts.

In the present embodiment of the invention I have illustrated the apparatus in connection with an automatic exposing or printing machine of the type above referred to, a conventional representation of which is indicated atl: This machine delivers the of Monroe and State of New York, have invented certam exposed negative or print 2 by any suitable means into a developing receptacle or tank 3 arranged immediately below the same and containing a suitable developing agent. What may be termed the rear end 4: of the receptacle 3 is the end from which the print is withdrawn for subsequent treatment, usually through a small opening 5 at the bottom of the casing of the machine 1 and arranged adjacent to said end a is the end 6 of an intermediate receptacle 7 that, in the present instance, is used for washing the print. The rear end 8 of this intermediate receptacle 7 abuts the front end of the receptacle 9 into which the print is finally introduced for fixing with hypo. One of the two abutting end walls in each instance is preferably provided with a depending apron 10 to prevent leakage of the liquid between the receptacles.

In the practice of my invention I provide the intermediate receptacle 7 near its front end 6 with receiving guides for the print as it leaves the receptacle 3. These guides, in the present instance, comprise a pair of alined rollers 11 preferably raised above the rim of the receptacle and journaled upon-the opposite end of a ball 12 extending transversely of the receptacle 7 and supported in any suitable manner, as upon uprights 13. .The intermediate portion of the bail 12 is offsetdownwardly, as at 14;, for a purpose that will hereinafter appear so that in effect the two receiving guides or rollers 11 are spaced apart at their proximate ends. At a preferably interme-' face level of the receptacle 7 as shown in Fig. 2, but the pivots 17 are above the surface level and also preferably above the rim of the receptacle.

In operation, the print 2, after being developed, is-brought to the position shown in Fig.=1 in which its edge is just above the adjacent rims of the receptacles 3 and 7. The operator then displaces the immersing -member 15 by thrusting his hand beneath it and moving it upwardly to approximately the position shown in 1 in which it is adjacent to the receiving guide rolls l1 and above the offset portion 14 of the bail 12. He can then thrust his fingers'between the ends of the rolls 11 and grasp the edge of the print, withdrawing it from the re- 4 ceptacle 3, over-the uide rolls 11 and down dragging portions immersed throughout the into the water bat in the receptacle 7. As he continues to draw the pr nt rearwardly, the immersing member follows by gravity and,-in dropping, thrusts. the body of the print below the surface of the water in thereceptacle and continues to' hold the passage of the print through this intermediate receptacle, and while the operator is introducing the advance edge over a suitable guide roller 19 at the end '8 of thereceptacle 7 and into the final or fixing bath in the receptacle 9. It will be'seen, therefore, that this transfer from the developing receptacle 3 through the intermediate I'e-.

ceptacle'and into the hypo, can be effected with a quick movement and in a very short space of time so that even though the rec'e'ptacles 7 and 9 are exposed to light the ing member 15 acts automatically in im-' print can undergo very little change before being fixed, while the washing operation in the intermediate receptacle 7 issufliciently thorough to. greatly lessen the deterioration of the hyp Which deterioration is" rapid when a diriect transfer is made from the developer thereto. ,The' rolls 11, 15 and 19 provide smooth and even frictionalrsurfaces for the wet and soft print, and the immersmersing'the last half of the print just as effectively as the operators hand immersesthe front half while being very readily displaced, and thus offering little inconven=- ience to the operator when reaching for the print in the first instance. r,

I claimas my invention:

1. In an apparatus of the character described, the combination with a suitable receptacle for the fluid bath, of supporting links pivoted to the receptacle on opposite sides thereof at' points above the surface level, and a transversely extending immersing member carried by the lower ends of the links in a normal face-level.

2. In an apparatus of the character set forth, the combination with a suitablereceptacle for the fluid bath, of a transversely extending receiving guideat one 'end of. the receptacle arranged above the rim thereof,

position below the sur supporting links pivoted at opposite sides J of the receptacle at points above the, sur- 1 face level and a transversely extending immersing member carried by the lower ends guides at oneend of the receptacle'having 'a' space between them, a transversely extending immersing member mounted onithe' having a normal posltion below receptacle the surface level and means for movin the immersing member from its said n'orm'a position upwardly to aposition adjacent to the receiving guides. i a 4. In an apparatus of the character described, the combination with a suitable receptacle for the fluid bath, of a transversely extending bail at one end of the-receptacle provided with an offsetintermediate por tion, guide rolls journaled on the end portions of the bail, a transversely extending immersing member mounted on the receptacle havin a nbrmal os'ition below the surface leve andmeans or moving the immersing member from its said normal position upwardly to'a position adjacent to the guide rolls and above theoifset portion of the bail Witnesses:
